SPECIFICATION forming part of Letters Patent No. 296,469. dated April 8, 1884.

Application filed August 20, 1853. (No model.)

To all whom it may concern."

Be it known that I, ALEXANDER GRAY SIMP- SON, of Arcadia, Missouri, have made a new and useful Improvement in Door, Gate, and Window Fasteners, of which the following is a full, clear, and exact description, reference being bad to the annexed drawings, making part of this specification, in which- Figure 1 is a viewin perspective of the improved fastener; Fig. 2, a front elevation, showing the device as when the door is fastened'; Fig. 3, a section on the line 3 3 of Fig. 2; Fig. 4, a front elevation, showing the device as when the door can be opened Fig. 5, a section on the line 5 5 of Fig. 4:.

The same letters of reference denote the same parts.

This improvement is adapted either to doors, gates, or window-sashes.

It consists, substantially, of a journal fastened to the fixed part of the structure-that is, the door-jamb, gate-post, or upper sash and provided with an adjustable arm, the journal and arm being so relatively constructed as to enable the-arm, when upon one part of the journal, to be rotated upon the journal, and thereby enable the door, gate, or sash to be opened, but when slipped onto another part of the journal to be prevented from rotating, and, in consequence, to become anobstacle to the opening of the door, gate, or sash.

A desirable mode of carrying out the improvement is shown in the drawings, where A represents the fixed part of the structure that is, in case of a door it would be the doorjarnb, in case of a gate it would be the gatepost, and when the device is used as a sash fastener the part A would be the upper sash. B represents the part which opensthat is, the door, gate, or lower sash. 0 represents what I term the journal, which is attached to the fixed partA in any suitable manner, so that the arm D can be operated as. described. A simple and suifioient mode is to provide the journal with points 0 c, which are extended and driven into the part A as if inserting a staple, and as shown in Figs. 2, 3, 4, 5. A portion, 0, of the journal is rounded to enable the arm D to turn thereon. Another portion, 0", of the journal is squared or provided with a shoulder, to prevent the arm, when upon that part of the journal, from turning. Vhen it is desired to leave the gate, door, or sash free, the arm is allowed to remain on the part c of the journal, as in Figs. i, 5, and when the door, gate, or sash is opened the arm Dyields and turns upon thepart dot the journal. When it is desired to lock the door, gate, or sash, the arm D is slipped onto the part c of the journal, as shown in Figs. 1, 2, 3. This prevents the arm from being rotated, and the door, gate, or sash cannot be opened.

I do not wish to be confined to the precise forms shown at c 0 in relatively shaping the journal and arm. For instance, instead of the square form shown in part c of the journal, a spline or any suitable shoulder can be employed, which, when the armD is slipped onto it, will come against a corresponding shoulder in the eye at of the arm and prevent the arm from. turning, and the part c of the journal need not necessarily be round, provided the eye d can turn on the part 0' The requisite is that the two parts 0 c and the eye at of the arm D shall be so relatively constructed as to enable the arm to turn upon the part c and be prevented from turning when upon the
